IGNATZ WEISE, OF PASSAU, GERMANY.

BICYCLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 585,067, dated June 22,1897.

Application filed December 24, 1896. Serial No. 616,924. (No model.)

To all whom it may concern:

Be it known that I, IGNATZ WEISE, a subj ect of the King of Bavaria,residing at Passau, Germany, have invented certain new and usefulImprovements in Bicycle-Brakes; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to improvements in bicycle-brakes; and it consistsin the novel devices hereinafter described and claimed.

My invention will be understood by reference to the accompanyingdrawings, wherein the same parts are indicated by the same lettersthroughout the several views.

Figure 1 represents a side elevation of my brake as applied to abicycle. Fig. 2 represents a front elevation of the same, and Fig. 3 isa detail view showing a short brake-rod held extended by a spring foruse with my brake when used as a foot-brake simply;

For the purposes of my invention the felly of the wheel is made to bulgeinwardly, as at A, and the sides a a of this bulging portion are formedin approximately parallel planes, as seen in Fig. 2.

The brake proper consists of a pair of double bell-crank levers O O,pivoted, by means of studs D D, to a pair of collars D D,

clamped upon the steering-forks X X near the steering-head X. Thependent arms G O of these double bell-crank levers O O carry brake-shoesB B, secured thereto by means of bolts 0, and these brake-shoes B Bcarry friction-blocks b b, of rubber or other suitable material. Thebrackets D D, towhich the double bell-crank levers O O are pivoted,should be'clamped upon the forks in such a position that when the brakeshoes are brought together they will bear upon the opposite faces a a ofthe flanges of bulge A of v the rim.

E, which brake-rod E passes through a guide sleeve E carried upon abracket mounted upon the front fork of the bicycle, as shown mostclearly in Fig. 1.

The brake is operated by the brake-rod being drawn upward instead ofbeing projected downward, as is ordinarily the case.

The double bell-crank levers O 0 have the outwardly-extending horizontalarms 0 C thereon provided with footrests, as shown in Fig. 2, by meansof which the brake may be operated by the foot or feet of the rider.

If desired, the brake may be operated by the foot or feet only, in whichcase the brakerod E might be cut off slightly above the guide-sleeve Eand have a pin or key 6 passing therethrough just above said sleeve anda coil-spring F surrounding the said rod between the sleeve E-and theforked end E of the rod, the said coil-spring serving to hold the brakenormally out of engagement with the wheel. This modification is shown inFig. 3, and it is obvious that the coil-spring shown in this figure maybe used with the form of brake-operating rod shown in Figs. 1 and 2, asdesired.

The operation of my brake either by hand or by foot is obvious and doesnot need explanation.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

1. In abrake for bicycles, the combination with a pair of collarsadapted to be clamped upon thesteering-forks; a pair of angle-leverspivoted to said collars, each having a depending arm thereon carryingabrake-shoe, and a pair of oppositely-disposed horizontal arms throughwhich the said depending arm is operated, the inwardly-extending arm ofeach angle-lever overlapping the corresponding arm on the otherangle-lever, and the two being provided with coincident slots therein,and the outwardlyextending arm of each angle-lever forming a foot-rest;of a vertically-movable rod mounted upon the steering-head and passingthrough suitable guides thereon, and having a forked lower end adaptedto fit over the said slotted arms; and a bolt passing through the forkedend of said rod and the slots in said slotted arms, substantially asdescribed.

2. In a brake for bicycles, the combination with a pair of doublebell-crank levers pivoted to the steering-forks, and each having adepending arm carrying a brake-shoe at its free end, and a pair ofoppositely-disposed horizontal arms, one of said horizontal arms on eachbell-crank lever extending inwardly and overlapping the correspondingarm on the other lever, and the two being provided with coincidentlongitudinal slots therein, and the outwardly-extending arm of eachbell-crank lever forming a foot-rest; of a vertically-movable rodmounted upon the steering-head and passing through a guide thereon andhaving a forked lower end adapted to fit
